Hey there, this is the deal. I have an older toilet in my basement bath that I replaced the innards in about a year ago. This toilet flushes with great gusto, however, 9 times out of 10, it refluxes back at the end of the flush bringing with it a portion of solid waste, thus requiring a second flush.
So, is there some adjustment in the fill level or something like that to stop this phenomenon? Thanks.

Are you sure that there is not a blockage or restriction in the drain?

If there is not a blockage or restriction then have the tank fill higher with more water.

The more water in the tank the less likly you will see any problems.

I also think the quality of the toilet bowl (shape/size) have also somthing to do with this phenomenon, may be the opening is not wide enough...etc... Although I am just guessing...

The fill level is adjustable, although for some of the replacement
"innards" you have too remove the valve to adjust it. Some of the newer kits also have some device that delays the flap from closing.

I think the "factory" setting for these is too low for older toilets. Try adding some water to the tank on a couple test flushes.
There are really two levels to be concerned with - the level in the bowl, and the tank.

I'v' seen some people route the refill tube directly into the tank, instead of the overfill tube. This causes the bowl level to be too shallow.

We can assume that you have a sewage ejector system in your basement and at the point of concern your drainage from the toilet to the basin and including the basin may begin to be full. The ejector engages, clears out the basin and the whole process starts over again. Consider adjusting the pump controls to turn the pump on sooner.
Here are som e examples of these types of systems - Sewage Ejector Systems
